### Description
Extend glob pattern matching support similar to .gitignore in .airflowignore
### Use case/motivation
I recently upgraded Airflow from version 2.6.2 to 2.9.2 and noticed a change
in version 2.6.3 related to .airflowignore handling. My requirement is to
exclude everything except certain folders within the dags_folder path.
Previously, I achieved this using pattern `^(?!(foo|bar)).*` with the default
`dag_ignore_file_syntax = regexp`. However, after the upgrade, this approach
stopped working because Google's RE2 engine doesn't seem to support `(?!)` as
expected. I attempted switching `dag_ignore_file_syntax = glob` and observed
that the current glob support is very limited. Hence requesting this feature to
provide similar functionality as of .gitignore where I can define the pattern
like `!{foo/*,bar/*}`.
